TROUBLESHOOTING
This troubleshooting guide is intended to assist you with certain
problems which may occur. If you still encounter problems, see your
Authorized Rockford Dealer for assistance.
Problem
Amplifier will not play — Remote Turn-on light is off.
Solution
1. Check the DC voltage at the amplifier’s B+ terminal with a
voltmeter. The voltage should measure between 11.5V - 15.5V.
If voltage is
not
found, check the battery, fuse, fuse housing and
wire connections. Fix, repair, or replace accordingly.
2. If the amplifier still does not play, check the voltage at the
amplifier’s remote turn-on lead. The voltage should measure
between 11V - 15V.
a. If voltage is above or below the prescribed measurements,
check for proper connections and have the head unit checked
by an Authorized Dealer or Service Center.
b. If the remote turn-on current draw from the head unit is
connected to multiple amps and/or electronics, the current
draw may be too great. Check for proper connections. (Use
a relay to suppress the excessive current draw.)
Problem
Amplifier will not play — Remote Turn-on light is on:
Solution
1. Unplug the head unit and test the amplifier with another working
source unit (i.e., bench-test radio, walkman, etc.). If the amplifier
plays, check the in-dash leads for cuts, breaks and/or shorts.
2. If the amplifier still does not play, disconnect the existing speakers
and connect a set of test speakers to the output of the amplifier
(any type of speaker will do - i.e., simple home box type,
bookshelf, raw speaker, etc.). If the amp plays, check for shorts
or blown voice coils in the vehicle’s speaker system.
